Iron is an essential micronutrient for plant growth and development. Under low iron
conditions, Arabidopsis plants take up soil iron using the root iron transporter IRT1. In …

Iron, an essential nutrient, is not readily available to plants because of its low solubility. In
addition, iron is toxic in excess, catalyzing the formation of hydroxyl radicals that can …

Plant roots forage the soil for iron, the concentration of which can be dramatically lower than
those needed for growth. Soil iron uptake uses the broad metal spectrum IRT1 transporter …

The past two decades of research on plant iron nutrition have completed the casting of the
major transporters involved in iron uptake from the soil, long-distance transport, and …

Iron is an essential micronutrient but is toxic if accumulated at high levels. Thus, iron uptake
and distribution in plants are controlled by precise regulatory mechanisms. IRON …

Plants are the principal source of iron in most diets, yet iron availability often limits plant
growth. In response to iron deficiency, Arabidopsis roots induce the expression of the …

In plants, iron uptake from the soil is tightly regulated to ensure optimal growth and
development. Iron absorption in Arabidopsis root epidermal cells requires the IRT1 …

Plants take up iron from the soil using the IRON-REGULATED TRANSPORTER 1 (IRT1)
high-affinity iron transporter at the root surface. Sophisticated regulatory mechanisms allow …

Main conclusion IRT1 intracellular dynamics and function are finely controlled through
protein–protein interactions. Abstract In plants, iron uptake from the soil is tightly regulated to …

Iron uptake from the soil is a tightly controlled process in plant roots, involving specialized
transporters. One such transporter, IRT1, was identified in Arabidopsis thaliana and shown …
